IFMA

The International Federation of Muaythai Amateur (IFMA) began as a small federation with several enthusiastic countries, more than two decades ago. After the passage of the initial stages of its life and at the dawn of an exciting new century, IFMA had grown to 130 member countries worldwide with 5 continental federations, together existing under a single, unified regulatory body.
